Areca Backup

Hello,
I often get the error message

Während des Vorgangs ist der folgende Fehler aufgetreten :
java.lang.IllegalArgumentException:
.cache/sessions/Thunar-11c0a8b228000119948559600000071130002
Bitte überprüfen Sie die Protokoldatei
(/home/philipp/.areca-workspace/log/areca.08-02-09.log) für weitere
Informationen.

The file which seems to cause problems does exist with access granted. It
is a 0 byte file, but the problem has also occured on several other
non-empty files before which I had to remove to make the backup work. The
log file is included as an attachment.

Areca of course runs on linux, "java -version" returns
java version "1.6.0_03"
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
Java HotSpot(TM) Client VM (build 1.6.0_03-b05, mixed mode, sharing)

The backup settings are as follows
<target id="7" uid="195415633" follow_symlinks="false"
follow_subdirectories="false" xml_security_copy="true" name="Home"

OK, so I just got to know by chance that when I switch to the english
language and restart the backup seems to work. Weird!


By the way: The available bug groups are not of current state.

Thank you for your effort. I hope I will get along with this bug by using
the english interface. That's no problem at all. But perhals you want to
look into it to clean up with this issue.
